  • Piping and tubing systems for industrial, automotive, recreational vehicles, HVAC ducting and other applications typically involve transport of fluids.
  • sleeves, covers or other similar elements are often provided over one or more portions of the pipes for thermal insulation of the pipe and/or the fluid transported therein, pipe protection, structural support and reinforcement of the pipe, and/or other purposes.

  • pipe insulation it is often crucial that the inner surface of the pipe insulation is positioned tightly, in a close fit, and/or without any gaps with the pipe surface to ensure that the sleeve remains in the desired position on the pipe and provides the required insulation or protection.
  • conventional band clamps may be employed to secure the insulation onto the pipe.
  • the deferring thermal expansion properties of the pipes and the pipe insulation causes unavoidable gaps between the insulation and the pipe thereby weakening the desired tight fit.
  • heat transfer from hot exhaust gases may cause an increase in temperature of the pipe and the insulation.
  • the metal having greater thermal expansion coefficients (for example, 2-10 times greater) in comparison with that of the composite insulation, the metal would expand much more than the insulation.
  • the increased expansion of the metal of the exhaust pipe, and particularly the outer circumference may exert hoop and radial stresses on the insulation causing the insulation to stretch along with the pipe.
  • the pipe, and consequently the insulation may return to their original dimensions once initial/ambient temperature and/or thermal equilibrium is restored.
  • the repetitive/cyclic stresses on the composite insulation may irreversibly modify the structure and dimensions of the composite insulation, such that the insulation is not restored to its original state.
  • gaps may be formed between the composite insulation and the pipe at one or more locations/portions along the outer surface of the pipe.
  • gaps may cause the composite insulation to dislocate/slip along radial and/or axial directions of the pipe, adversely affecting the insulation and protection of the pipe by the composite insulation.
  • this dislocation/slip may be exacerbated by the vibration and other operating conditions of the pipe, requiring the insulation to be replaced often.
